A note about Borosilicate glass:Borosilicate glass is a premium glass used to make vessels appropriate for everyday use. Unlike other glass, it does not crack under extreme temperature changes, making it suitable for putting in the dishwasher. Borosilicate glass is made up of about 15% boron trioxide, an ingredient that changes the behavior of glass and makes it thermal shock resistant. This allows the glass to resist extreme changes in temperature—borosilicate glass has the ability to go straight from a freezer to an oven without cracking and withstand temperatures of up to 932 °F. And so, this glassware can be used for both hot and cold beverages.

R&D uses borosilicate glass made by the company that invented it in 1893! Using borosilicate glass leaves a low carbon footprint as it is made from naturally abundant materials and do not require excessive mining. If handled with care, borosilicate glass will last a lifetime.
